What are the two main types of machine guns used in modern warfare?

The classification of machine guns into general-purpose and heavy machine guns reflects the varying roles these weapons play on the battlefield. General-purpose machine guns are designed to perform multiple roles, offering versatility in both support and offensive operations. They typically have a lighter construction, allowing for ease of movement and deployment by infantry units. These machines can be used for sustained fire in both offensive and defensive capacities, making them suitable for various tactical situations.

On the other hand, heavy machine guns are usually mounted on vehicles or used in fortified positions due to their increased weight and firepower. They are capable of delivering a higher volume of fire and can penetrate stronger targets, making them essential for anti-vehicle missions or to provide a substantial suppressive effect against enemy forces. The distinction between these two types of machine guns illustrates the spectrum of capabilities available to military forces, highlighting how each type is optimized for specific operational needs in modern warfare.
